Other mistake: In the famous mugshot of Walter against a height chart, the chart goes up in nice 2 inch increments until 5'8." It then jumps to 6'0", completely skipping 5'10". Did they forget there are 12 inches in a foot, not 10?
Other mistake: Throughout the show, during the into credits, people's names have 1 or 2 letters replaced by green characters to symbolise elements from the periodic table. However, Michael Slovis has the 'Ch' highlighted. There is no 'Ch' on the periodic table. (00:03:20)
Other mistake: When the bear is falling through the sky after the plane crash, it is shown through its point of view. When it starts falling, a shot of northern Albuquerque is shown but when the bear turns over, suddenly it is facing the east. Eubank Blvd is a major north and south street, is seen in the shot of the north. In the latter shot, Candelaria Rd, which is a east and west street is visible. When the bear spun over, it should be showing Eubank Blvd going south.
Other mistake: Walter's pants flying in the air defy the laws of physics. The RV is racing forward and the pants somehow find themselves in front of the RV floating through the air. One could say that the pants perhaps flew forward when the RV 'hit a bump' perhaps. However the RV would have to hit a considerable sudden stop to get the pants to fly forward. The RV then runs over the pants which have fallen to the ground from in front of the RV. This could be ignored as somehow possible due to some strange anomaly. Except near the end of the episode. We see the same pants fly off the mirror of the RV flying backwards. Making it impossible for those same pants to be run over from in front of the RV especially due to the speed at which they are flying backwards straight into the camera shot. (00:00:15)
Other mistake: The configuration of the front side of the house does not match the configuration from the inside. The outside view looking at the house from the street indicates (1) there are no rooms to the right of the garage (when inside there are rooms on the side of the garage). Also when looking at house from street side, to the left of the front door the house comes forward. When inside, (at least in episode 13, season 3) the inside of the house does not extend forward towards the street.
Other mistake: When Walt is ringing Jesse to find out where he is, the call goes straight to voicemail. However, when he rings Jesse from inside Jesse's bedroom, the phone rings before going to voicemail. The mistake being that the call should have gone straight to voicemail. (00:41:00)
Other mistake: At an RV park, Hank is investigating an RV that looks like the one he saw in the pictures from the ATM camera. Desperate for a vantage point, he goes around to the back of the RV and starts to climb up the ladder on the passenger rear side of the vehicle. This RV is not supported at this time in a permanent fixture, as it's revealed shortly there after that the occupants were just on vacation. So Hank's full body weight getting on the back corner of the RV should have shifted it on it's suspension and alerted the people inside that something was going on far sooner than it did.
Other mistake: At the end, we see the gunfight between Tuco's cousins and Hank. Several shots are fired, cars smash into each other, a woman runs off screaming. So not a "quiet" attack. However, as the camera zooms out to show the carnage, 2 people who are not involved in the attack, are just stood talking in the car park. A bit odd since there has been a very clear shoot out.
